you have a set of these planets? Nice. Perhaps you can motorized them as well.

I'm probably missing some context to understead what your are saying.

While working in the software, which btw still isn't finished, I noticed that some arms were still brushing against eachother, moving one where it shouldn't. I had 1mm tolerance, but I'm now finalizing a design with 2mm tolerances. I have a remark in the instructable about this. If everything goes well, it should have an updated link to download, you don't have to redo everything only the ones with a capital N at the end. Actually you don't have to redo anything if yours works fine with the 1mm tolerances. The file includes the missing icons.

well not quite, that one is geocentric and has 35 gears! In principle there is nothing wrong with a geocentric view, if you want to know in which direction you can actually see the planets, but for this model I used a heliocentric approach and only 1 set of gears to transfer power from the motor to the mechanism.

@@illusionmanager very nice implementation indeed

already did :-) www.instructables.com/Astronomical-Clock-1/

I used the depth image from the kinect attached to a laptop. analyzed the image and send it to the cube which has a usb connector. That's a bit vague, but it was a home build cube, so the protocol is very specific for this cube

@@illusionmanager I have a project I’m working on at the moment, curious if you’d be interested in creating something similar to this on a different cube? :) is there another way I could contact you by chance?

@@kvmuse2694 this too long ago, and if I remember correctly it only worked with the first version of the kinect. someone wrote some documentation of how to get the depth map from a kinect.

That's funny as this name is a contraction of Zambra and Negretti. Follow my instructions on www.instructables.com/Negretti-Zambra-Pocket-Weather-Forecaster/ to make one yourself.

I'm thinking about it, but don't have the right idea that would look good. Any suggestions?

@@illusionmanager laser cut each section and cover in gold leaf?

I made an instructable and published it here: www.instructables.com/High-Resolution-Ticker-Video-LED-Panels/

relatively straightforward indeed...for range of years. The moon is a bit more complicated. Getting data directly from NASA sounds cool anyway.

because the esp32 microcontroller in the sun also acts as a webserver, which allows me to set it to any date between 9999 BC and 9999AD. Neptune moves a lot in that time. The Zero position (equinox) is currently parallel to one of the walls in my house. But yeah, it is missing a zodiac, I just don't know yet how to keep that beautiful and minimalistic. Who knows.

@@illusionmanager I thought it only showed the current state, not that you could change it.

have a look here www.instructables.com/Grand-Planet-Spinner/ where I posted the instructions for two different versions, using almost the same principle.

Clever idea, but only useful if the relative distance to the sun would be correct as well. Currently it only shows the direction, which is still accurate, even when not taking into account the eccentricity.

The woodwork is the same, but it needs different wiring and a 10k resistor to do the serial communication.

sure, that's the first thing, If you only would look for a single value you forecast might be fine, but the challenge is to make it better and use basic meteorological knowledge. A passing low pressure area has some characteristics. Falling and rising pressure is already a great improvement. Many barometers have therefore an option to compare the pressure with previous measurements. The barometers with a dial, almost always have a little knob in the center to rotate a little pointer to the current pressure. When you look at it later you can see if pressure is falling or rising. The zambretti forecaster uses that info. Incorporating the wind direction is another great improvement. And you'll get a little improvement from the difference between summer / winter. Perhaps you have gathered enough data to optimize for these parameters as well.

@@illusionmanager I intentionally took data over a very long period of time, spanning several years. These data were collected by meteorologists every 3 hours and entered into a database. As a result, I have a table of 48,675 entries for each parameter! I analyzed pressure, temperature, wind, and humidity. However, pressure had the highest reliability. All other parameters did not show any obvious correlation with rainfall. In addition to pressure, I can cautiously recommend using relative humidity to forecast precipitation if it exceeds 75%. However, it can change very quickly before rainfall and not every sensor can detect it. It is preferable to use an Assman psychrometer with forced aspiration for such measurements. This way, an accurate result can be obtained in 2-3 minutes. Other sensors are likely to have greater errors.

@@user-zp2hf6hw4h That's a good amount of data, but surely you should be able to find in that data, that when pressure suddenly drops that you are likely to have rain and things like that.

@@illusionmanager It should also be taken into account that atmospheric pressure has a diurnal variation. It rises and falls twice a day at certain times. To determine whether the pressure is rising or falling, it must be compared to the difference in readings over a day. This can be used to make long-term weather forecasts for 3-4 days. However, if the pressure does not have time to become low during this time, there will be no precipitation, even if it is decreasing.

@@user-zp2hf6hw4h unless you live in the tropics the diurnal variation is less than 1mbar, not enough to make a significant change. a 1mbar change in pressure, during 3 hours is probably just considered "steady" and not falling or rising. Changes in atmospheric pressure often, but not always, predict the weather. Falling pressure suggests that a low-pressure zone with wet, stormy weather is moving your way. Rising barometric pressure is often, though not always, a sign that the weather will soon clear and turn fair and sunny. You should be able to find that in your data.

only seven panels

i bought them here when they were about 75% the current price www.aliexpress.com/item/1005004919622952.html

i made an instructable. Have a look here www.instructables.com/Negretti-Zambra-Pocket-Weather-Forecaster/ it has all the images you need to make one yourself

@@illusionmanager Thank you very much

no, the mouse has no name.

The video just shows some of the different clock faces. But because of the stop-motion animation it isn't very clear how to read the time from pingo's default face (shown at the end of the movie). There are three rings of color. The middle one shows a rainbow. The outer ring shows a solid color and at some point it matches the color of that rainbow. That's the location of the minute hand. Similarly, the solid color of the central part matches the rainbow at the location of the hour hand. In this case it is 10:25

Did you read the description that comes with the video?

@@illusionmanager I did, but I still did not understand. It doesn’t look projected from the outside like the other things. Maybe it’s just an optical illusion. Whatever it is, it’s awesome as is the rest of your display.

@@gregg5958 it is indeed just projected. I printed it using a bit translucent material.

@@illusionmanager Ah okay. Interesting. That really made a difference. I need to experiment more. I never would have thought to use that.

can't remember. Perhaps i just kept a module attached electrically and put it somewhere aside.

the robot you see is actually a 3d printer (as can be seen in de video). It is controlled by sending it commands in gcode via WIFI

the bar was a left over from some TV lifting setup. You could use a piece of wood instead. The dispensers were a birthday present a long time ago, but you can find similar ones easily on for example amazon.

those are Twinkly lights.

Mostly using a 360 camera
